its definatly a Renault with the yellow nose and black front wing. im going to go with a renault RE30B or a Renault RE50 (seeing as the rE30 and 40 have both been gessed its just process of elimination now)
Again, the driver is noteworthy. The car is probably obscure enough that I could post it un-blurred, if it didn't have the name and numbers plastered all over it.
It's not one of the Le Mans winning Matra's is it, and Pescarolo is driving?
The Matra-Simca MS670C, and I'll guess at 1974 (the last of three year straight win run it had).
Well, considering the 670C and 670B only have minor differences to the 670 it actually is in that photo... I'd say Duffers, since he was the first to post a 670-type car.
And I thought the 670 was obscure myself - despite being a Frenchcarophile and read about Matra's F1 efforts, I never thought of checking up on their Le Mans history.
